Development of functional active films from blend of gelatin with crude orange juice pomace pectin: Test for packaging of virgin olive oil
Bovine gelatin blended with polyphenol-rich orange juice pomace pectin was used to develop an active film. This film exhibited potent antioxidant and photoprotective properties. When designed as a pouch, it has effectively delayed the oxidation of virgin olive oil over 63 days of storage, all while maintaining its sensory characteristics. AbstractThe food packaging sector is focused on developing innovative materials to enhance food safety and quality while reducing environmental impact. Accordingly, this study aimed to develop packaging based on bovine gelatin (G) blended with crude sweet orange juice pomace pectin (SOPP)...

Leaking Gut, Leaking Blood Vessels, Leaking Blood Brain Barrier
In today's open access paper, researchers attempt to throw a big tent over three distinct issues in the aging of the body and brain. Firstly, the intestinal barrier fails, allowing bacteria and bacterial metabolites into tissue and the circulation, where they can provoke dysfunction and inflammation. Secondly, blood vessels become leaky, harming surrounding tissues by allowing excessive fluid, inappropriate molecules and cells to escape. Lastly, the blood-brain barrier leaks; this is a more specialized barrier layer surrounding blood vessels in the brain, and when it leaks, the passage of unwanted cells and molecules into ...

Assessment of chemical compositions and antibacterial activity of the essential oil of < em > Mentha piperita < /em > in response to salicylic acid
Nat Prod Res. 2023 Sep 13:1-12. doi: 10.1080/14786419.2023.2256020. Online ahead of print.ABSTRACTMentha piperita, as a species of the mint family, is used in various medical, cosmetic, industrial and culinary products. The effect of different concentrations of salicylic acid (SA) (0. 0.5, 1 mM) on phytochemical activity and antimicrobial potential of Mentha piperita essential oil against six human pathogenic bacteria (Streptococcus agalactiae, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus and Listeria monocytogenes) were investigated. According to the results to prevent the growth ...

< em > Salvia dumetorum < /em > essential oil: GC-MS analysis, antibacterial activity and effect on the formation of < em > Streptococcus mutans < /em > biofilms
In this study SDEO was screened for its antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Candida albicans and the amount of biofilm formed by Streptococcus mutans bacteria. For the first time the chemical composition of SDEO growing in Central Kazakhstan was established. The results obtained from GC-MS showed the predominance of sesquiterpenoids (54.15%). The antibacterial study results showed that SDEO exhibited strong antibacterial activity against B. subtilis and S. aureus in vitro and also demonstrated an inhibitory effect on S. mutans biofilm formation on 1% sucrose medium...

Antibacterial activity and mechanisms of α-terpineol against foodborne pathogenic bacteria
This study aimed to evaluate the antibacterial activities of α-terpineol against common foodborne pathogenic bacteria by agar well diffusion, broth microdilution, and colony counting assay. Propulsive research was conducted to reveal the antibacterial mechanisms, including morphology, infrared spectroscopy, membrane fluidity, membrane permeability, proton motive force, and oxidative phosphorylation. Results indicated that the antibacterial activity of α-terpineol decreased in the following order: Escherichia coli O157:H7, Salmonella typhimurium, Listeria monocytogenes, and Staphylococcus aureus. With an initial cell coun...

Impact of the TLR4 agonist BECC438 on a novel vaccine formulation against Shigella spp.
Shigellosis (bacillary dysentery) is a severe gastrointestinal infection with a global incidence of 90 million cases annually. Despite the severity of this disease, there is currently no licensed vaccine against shigellosis. Shigella’s primary virulence factor is its type III secretion system (T3SS), which is a specialized nanomachine used to manipulate host cells. A fusion of T3SS injectisome needle tip protein IpaD and translocator protein IpaB, termed DBF, when admixed with the mucosal adjuvant double-mutant labile toxin (dmLT) from enterotoxigenic E. coli was protective using a murine pulmonary model. To facilitate t...

Identification of unique indolylcyanoethylenyl sulfonylanilines as novel structural scaffolds of potential antibacterial agents
Eur J Med Chem. 2023 Aug 30;260:115773. doi: 10.1016/j.ejmech.2023.115773. Online ahead of print.ABSTRACTThe increasing incidence of antibiotic resistance has forced the development of unique antimicrobials with novel multitargeting mechanisms to combat infectious diseases caused by multidrug-resistant pathogens. Structurally unique indolylcyanoethylenyl sulfonylanilines (ISs) were exploited as novel promising antibacterial agents to confront stubborn drug resistance. Some prepared ISs possessed favorable bacteriostatic action towards the tested bacteria. Especially, hydroxyethyl IS 14a exerted 8-fold more potent inhibitor...
